substitute for the ordinary gate-valve for controlling and regulating the passage through a line of pipe; but it is particularly adapted for use as a valve for controlling and regulating the water-supplyin connection with' Water-closet ushing-valves', and it is inassociation withthe latter that my invention has therefore been illustrated in the accompanying drawings.

In such drawings, Figure 1 represents a middle vertical section of a flushing-valve of familiar construction with the valve constituting my present invention located inv the supply-pipe to which said flushing-valve is connected; Fig. 2, a vertical cross-section through the middle of the coupling-nut approximately on the line 2 2 of Fig; l and showing-the parts within the nut in elevation; Fig; 3, a perspectiveview of the parts within the coupling nut or sleeve with the latter and one of the rubber gaskets or packing-rings removed; Fig. 4, a perspective View of the valvedetached, and Fig. 5 a sectional detail showing a dierent methodof supporting the valve in the pipe-section upon which its seat is formed.-

The same letters of reference are employed to indicate corresponding parts in the several views.

A and B may be taken to be two sections of pipe coupled together by a coupling-nut C, engaging a peripheral ange upon the section A and screwed upon the exteriorly-threaded end of the sectiony B, as usual; but in the instance illustrated in the drawings the section B forms an integral -part of the casing of a water-closet flushing-valve D, While the section A is a short piece of pipe interiorly threaded at its end opposite the coupling for the purpose of screwing it onto the supplypipethrough which water is supplied to the valve D to iiush the closet with which the lower end of the valve is connected. It is desirable in flushing-valves of this character to provide a regulating-valve by means of lwhich the supply of water admitted to the fiushing-valve may be regulated at will and by means of which also the supply of Water may be entirely cut off from the flushingvalve when desired to permit the latter to be removed for inspection and repairs, and I have by my present invention provided a simple and eiicient valve for this purpose which is located directly in the pipe connections bctween the flushing-valve and su pply-pipe and which may be manipulated to regulate the quantity of water admitted to the flushingvalve or to entirely cut it off when necessary. For this purpose the end of the pipesection -A adjacent the section B issuitably formed to serve as a seat for a disk valve E, having a beveled seating-surface and carried in the present instance by an eXteriorlythreaded sleeve F, screwed into the pipe-section'A, the latter being interiorly threaded to receive it. The valve E is connected to the sleeve F by integral intermediate lugs a, which leave wide openings between the sleeve and lvalve for the passage of the water, Fig. `4. Upon its opposite side the valve E is provided With two diametrically opposite ears b, 'grooved to receive a pair of fingers c, projecting from a loose ring G, which tits between the abutting ends of the pipe-sections A B within the coupling-nut C and is free to turn independently of them. Owing to the connection of thepvalve E with this ring G by means of the grooved ears b and the fingers c, the valve and ring turn together, while the valve is free to move longitudinally of the pipe-sections independently of the ring, its grooved ears b sliding along the fingers c in such movements. By turning the ring G in one direction or the other, therefore, the valve E will be turned in a corresponding direction and -its threaded sleeve F be screwed farther into the pipe-section A, and thereby carry the valve toward its seat, orbe withdrawn therefrom to carry the valve away from its seat, according to the direction in which the ring and valve are turned. As a means for turning the ring G for this purpose I provide its periphery with a series of notches or recesses adapted to be engaged by a turning instrument inserted through an opening provided for the purpose ICO in the coupling-nut C. In the present instance I provide said nut at diametrically opposite points with interiorly-threaded bosses d, adaptedh to receive the threaded end ot a tubular turning-handle H, which contains a longitudinally-movable rod I, projecting at both ends beyond the tube and having its end adjacent the threaded end of the tube formed into a beveled pawlvtooth e, adapted to pass through openingsfiu the nut C at the bottoms of the bosses d and engage the notches in the periphery of the ring G, Fig. 2. The

opposite projecting end of the rod I-at the outer end of the tubular handle H is provided with a milled thumb-piece g, by means of which the rod may be drawn outwardly within the handle to disengage its inner end from the ring G. A coiled spring J, surrounding the rod I within the handle H and contned between shoulders formed upon the rod and handle, respectively, serves to press the rod inwardly and yieldingly maintain its toothed innerend in engagement with the ring G whenever the handle is applied to ythe coupling-nut.

Rubber gaskets or packing-rings K are interposed between the pipe-section A1B and the ring G upon either side of the latter for the purpose of making tight joints between the pipe-sections and ring. The couplingnutO is screwed upon the-threaded end of the section B tightlyenough for this purpose, but not so tightly as to prevent it from being turned freely back and foith a limited distance by means of the handle lI.

Under the above-described construction and arrangement of the parts the operation is as follows: Assuming that it be desired to change the existing adjustment of the valve E, so as t0 permit more or less Water to pass to the iiushing-valve or to cut it ott' entirely, the handle H isscrewed into one ofthe bosses d of the coupling-uut C and the paWl-tooth ev upon theinnerend of the spring-pressed rod I permitted to pass through the openingfin the nut Gand engage the peripheryof the ring G, as in Fig. 2. By now oscillating the nut C back and forth through a limited distance, using the handle II as a lever for that purpose, the toothed inner end of the springpressed rod I will engage successive notches in the periphery of the ring G and carry it forward continuously in one direction or the other, the beveled end of thetooth permitting itto slip backward over the ring in one direction without turning it, the latter being yieldingly held from movement by its frictional engagement with the gaskets K onA .either side of it.

Inasmuch as the valve E turns with the ring G, as before explained, and is supported by its threaded sleeve F in the pipe-section A, it will be carried toward or from its seat by such oscillation of the nut C, depending upon the direct-ion in which the ring G is turned thereby. This direction will depend upon the position of the beveled lower end of the rod I relatively to the ring. This rod is'free to turn within the tubular handle H when the latter is detached from thenut C or when after being attached the rod 'I is drawn outward against the resistance of the spring J (by means of the thumb-piece g at of the nut by means of the handle H. The

thumb-piece upon the outer end of the rod I is preferably provided upon its face with an arrow, Aas indicated in Fig. 2, to indicate the position of the tooth at its lower end and the consequent direction in which the valve will be turned by oscillation of the nut O, andthe nut vO may itself be suitably marked upon its periphery to indicate in which direction thev valve should be turned to close it and in which direction to open it.

. It will be understood that the handle H will be applied to the coupling-nut only when it is desired to adjust the valve, said handle constituting simply a key or tool to be kept on hand for adjusting all of the Valves in use at any given place. Cap-nuts L, screwed into the bosses d of the nut C, may be provided, as in the case of the lower boss in Figs. l and 2, to form a neat nish.

Instead of providing the valve E with the threaded sleeve F for adjustably supporting it within the pipe-section `A it may be, as shown in Fig. 5,V providedwith a threaded stem E', passing through a diametrical supportingbridgeE in the section A.
